Abstract
988,381. Grinding rotary tools. W. S. VICKERMAN. Feb. 15, 1962 [March 6, 1961], No. 5863/62. Heading B3D. A grinder for rotary tools comprises a beam 36 mounted at one end adjacent the grinding wheel W so as to be adjustable about vertical and horizontal axes transverse to its length, an indexing head 10 mounted on the beam for adjustment along it, a chuck or spindle 14 which receives the tool coaxially and is mounted in the indexing head for adjustment about its axis, and indexing means for adjusting the chuck or spindle about its axis, all the adjustments referred to being capable of being made independently to enable a variety of tools to be ground. The beam is pivotally mounted in a head 62 so as to be swingable vertically about the axis of a hinge pin 56 and set in desired position by screws 68, adjustment of the beam along the pin 56 also being possible. The head 62 is carried by a vertical pivot mounting 72 to permit horizontal swinging of the beam, this mounting being carried by slides 77, 78 permitting its accurate positioning. The head 10 is adjustable along the beam, micrometric adjustment being effected by a feed screw 48 threaded in a block 42 which is lockable in adjusted position on the beam by a screw 44; a screw 39 fixes the head 10 in adjusted position. The spindle 14 has an indexing ring 20 secured to it be a lock screw, this ring being provided with recesses 23 for co-operation with a spring- biased indexing head pin operable by a handle 28.
